yes, and for that they will or might have their crowd.
One of the games that I liked for the ps2 was "The Getaway", which will come out for the ps3, but im not sure about the xbox 360.
Watch this video. Its pretty interesting, about ps3's home. The online thing:

So I dont reaaally know. Then you get the whole other thing of, "will GTA IV look better on the ps3 or xbox360?" kind of thing. Just a random game, but I hope that there wont be much of a difference.
Like the game Assassins Creed, the producer or I forgot who, (it was a woman), said that they are going to make identical graphics etc, for both the consoles..
For me, im getting both actually, and I already have the xbox 360
